Wardrobe update at Prada

I moved about a year ago across country and decided I am starting a new wardrobe with high end pieces that will last a long time and that I am very proud of. This fall I am setting up an appointment with my local Prada to get in some menswear clothes. I was wondering if anyone knows the prices for Prada clothing. I cant find the prices anywhere. I am looking to get a pair of dress pants, a sweater, a casual shirt and a white dress shirt. What should I be expecting to spend? Thank you for your help.

Thank you for your replies. I am waiting for the sales associates at Prada to get back to me to see what they can get in. In the meantime I am going to look into all of your suggestions. I wish I was close to some nice outlets but I live in Arizona.
